摘要
φ220mm精密管材矫直机是目前国内直径最大的精密管材矫直机,该机在矫直辊辊型设计、辊系布置以及主辅机机械设备设计上具有较显著的特点,尤其是具有自主知识产权的精密辊系布置方式(半开放式交错辊系布置),在同等辊数的情形下,矫直精度远远大于其它矫直机组。简要阐述了φ220mm精密管材矫直机的技术特点,探讨了使用过程中显露出来的不足,并给出了处理措施,对今后精密管材矫直机的设计和使用有一定的参考价值。
At present,leveler of φ220mm precision tubular is domestic machine of precision tubular with the maximum diameter,which has remarkable characteristic on the design of leveling roller,the arrangement of roller system and the design of main and assistant equipment,especially owns independent intellectual property rights about the arrangement of roller system(the arrangement of ajar interlaced roller system ajar),under the same quantity of roller condition,the leveling precision is higher than that of other leveling unit.This article briefly states technical characteristic of leveler of φ220mm precision tubular,and discuss shortage occurred during usage,and also proposes disposal measure which provides reference to design and application of leveler of φ220mm precision tubular.
